Abstract: 978,939. Recording gramophones. AUTOPHOTO CO. June 19, 1961 [June 20, 1960(2)], No. 22098/61. Heading G5R. A customer-operated recording gramophone, on the insertion of a first coin, makes a recording on an endless magnetic tape, which is then played back for the customer's approval; the insertion of a further coin then cuts a gramophone record for delivery via a shoot 29. A foil on the magnetic tape and the coin-switches operate a logical relay sequence (Figs. 15a, 15b, not shown) to control the magnetic recorder (not detailed) and three motors feeding records to the disc recorder, driving its turntable and driving the recording stylus, respectively. Feeding record blanks to disc recorder. Blanks 24 are interleaved in two rows on the rails 36, 40 of a carriage driven along runners 35 by a spring 37. A motor and reduction gear (Fig. 3 not shown) rotate a double-ended lever 46 carrying a pin 47 which oscillates an anchor-form assembly 52, shown in one of its extremes of movement. Successive half-turns of the lever 46 cause a block 53 to displace the foremost-stacked blank outwardly, movement being halted at each half-turn by one or other end of the lever 46 operating a 'stop' microswitch 56. The springs 37 then advances the carriage to present the next blank to the assembly 52. The blank falls directly or via a ramp 28 into confronting relationship with the turntable 65 being caught by the lugs 90 of a member 89, retractable at a later stage to discharge the completed record to the customer through a slot 30 in the enclosure 21. Should the customer elect not to have a record cut, a seat-operated switch in the booth &c. (not shown) acts to erase the tape recording and restore the system to its 'stand-by' state. Disc recorder operation. A motor 112 and reduction gearing drives a worm-wheel 115 at the rate of one revolution per circuit of the magnetic tape and carries a radial cam 119 and a face cam 120. The radial cam, of stepped spiral form, operates a follower 123 attached to a Z-lever 125 to swing the stylus arm 97 across the record face while the face cam operates a lever 130 via a follower 129. This lever acts on spring-loaded members 85, 92 to advance and withdraw a pressure plate 74 and to advance and withdraw the stylus from cutting position. In the blank-loading position shown, a blank is picked off the lugs 90 by the point 91 and pressed against the turntable 65 by a rightward movement and the lugs 90 are sufficiently withdrawn to deliver the record by a leftward movement, any tendency of the record to stick to the pressure plate 74 being prevented by fixed stripper members 110. The rightward travel of the stylus arm 97 is limited by an adjustable stop 109 and stylus pressure, exerted by a spring 106 via a pivot 100 is limited by a screw 104. Miscellaneous features. A simplified, but quicker-acting embodiment (circuit, Fig. 16, not shown) and using the same disc recorder, on the receipt of a single coin, proceeds to make a tape recording and forthwith to cut a disc from it, sound being simultaneously played back. A vacuum fan, associated with a conduit 196 to remove cuttings, is energized when the turntable motor 69 is energized. A clock-form timer, energized when the tape recording is being made, shows the elapsed and remaining available programme time.
